OK, quick one to start with.....

Out Of range Calibrations

{H0139} Driven Wheel Rolling Circumference, was out of range when loaded.
{H0140} Non Driven Wheel Rolling Circumference, was out of range when loaded.
{H0152} Driven Wheel Pulses Per Rev, was out of range when loaded.
{H0153} Non Driven Wheel Pulses Per Rev, was out of range when loaded.


All of these have defaulted to the lowest setting which means they were probably set to something below the minimum settings. I have no idea why this would have been done, though maybe it was a speed limiting thing.

Given it's an auto, this may be messing with a number of other settings. If the diff gears and rear tyres are stock sizes, then I'd put the settings above back to the stock settings.

thanks

also this unit has stock injectors and a stock mass and the mass freq. has been changed and also the injector flow rate is changed .i was wondering about these.
all ive done so far is to read both tunes and compare as ive havent done a boosted unit untill now
